Replacing mechanical potentiometer with digital potentiometer for myRIO


I wish to replace a mechanical potentiometer on a motor control board which is used to control the speed of a motor with a digital potentiometer. This will allow me to control the speed of the motor using LabVIEW on a PC. I have a myRIO 1900 series.

I am looking for some help with the wiring involved in the removal of the existing pot and replacing it with the digital pot.


Thanks in advance.

Most digital potentiometers are I2C or SPI.

Does the myRIO have either?

The digital potentiometer is SPI compatible (attached).


The myRIO has SPI also.
